Only Superman has X-ray vision.  Besides, engines have a tendency to stop 
rotating in the same place each time, and that part of the belt tends to sit 
in a curve under tension through a hot-cold cycle, and is then asked to flex 
again the next day.  Inspect it by all means, but set an absolute upper limit 
of 50k miles (my personal opinion - my own ur-quattro sees a new belt a little 
more frequently, and the Coupe GT will not see another).
